This Instant Pot Broccoli Cheese Soup is creamy comfort food made in a pressure cooker. It’s healthy, keto, and low carb.
Before I started a low carb diet, I loved getting broccoli cheddar cheese soups at Panera Bread on rainy days. Even better if it was in a bread bowl. There’s something very comforting about cradling up to a warm bowl of creamy and thick broccoli soup on a cold day.
Now that I follow a keto diet, I make a healthy and homemade version of Panera’s soup from scratch. Unlike Panera, I skip thickeners like corn starch and flour. I don’t use chicken broth or stock because they often contain fillers and additives that I don’t think are necessary. I make up for all of this by adding in extra cheese and broccoli, and the end result is a very thick and hearty soup.
With the pressure cooker, it doesn’t take long to cook all of the ingredients into a state of creamy tenderness. Just 15 minutes of prepping and 15 minutes of cooking. It’s a fast recipe that yields five hearty servings, each filling enough for a meal.
I developed this recipe for the Instant Pot pressure cooker by adapting from my stovetop broccoli cheddar soup recipe. The two recipes are nearly identical, except that I don’t add bacon to the pressure cooker version for simplicity, and the pressure cooker version is a bit faster to make. Due to the differences in stovetop vs pressure cooking, this Instant Pot version is thicker and creamier because the ingredients are more broken down, resulting in more of a pureed taste.
Tips on making successful broccoli cheese soup in the instant pot:
- Interested in making this a no-chop recipe? You can make your prep work almost nonexistent by buying a bag of pre-chopped broccoli florets and a 15 oz container of mirepoix at the grocery store. Mirepoix is packaged and pre-diced carrots, onions, and celery, typically used as a flavor base for soups and stews. I pick up both at Trader Joe’s.
- Measure out the broccoli and cheddar cheese by weight. Here’s a great digital food scale. It’s a lot more accurate because depending on how they’re cut and shredded, the same weight of broccoli florets and cheese can vary significantly in volume.
- I use a pressure cooker made by Instant Pot and it has a 6 quart capacity. Either 6 or 8 quarts will work for this recipe, but I don’t recommend using smaller sizes.
- For an even thicker soup, you can use an immersion blender to puree. I prefer a chunkier soup so this isn’t something I do, but it’s a great option for those who prefer a smoother consistency.
- To further reduce the number of carbs, only use half as many onions and carrots. It’ll be thinner, but still delicious.
This recipe is ideal for preparing meals ahead of time because it cooks quickly, makes many servings, and freezes/reheats well. If your pressure cooker is large enough, you can double the ingredients (but keep the pressure cooking time the same) and make 10 servings. Each serving is about 1.5-2 cups in volume. You can store it in the refrigerator and reheat using the microwave, or you can freeze and reheat using the microwave at 50% power, pausing to stir every few minutes.

Very yummy! I doubled the recipe so I doubled the water. Should I have only used 2 cups of water for the broccoli? It wasnt as thick as I thought it would be but Im sure thats why. I added extra salt and cheese to compensate! Very yummy flavor! I will be making it again for meal prep! Thank you!
Thank you for your feedback! If you doubled the recipe, the water should also be doubled. If it wasn’t as thick as you thought, my guess is maybe you added broccoli and cheese by volume instead of weight? Depending on how you cut the broccoli florets (small or large) and how much you pack the cheddar in a measuring cup, the same amount can vary a lot in volume. If you make it again, I’d recommend measuring them by weight. Glad to hear you enjoyed it, and I hope you make it again soon!
Can i ask, how much is one serving? 1cup? 1/2cup?
Each serving is about 1.5 – 2 cups.
This sounds like a great recipe and versatile too (think cauliflower or broccoli/cauliflower). I have a 5 qt instant pot and wonder why you recommend only a 6 qt or larger.
I recommended 6 qt or larger because there’s a large volume of ingredients, but I think it’ll probably all fit in a 5 quart pot. Just might be a bit tight after you add cream and cheese.
I have frozen broccoli. Will the soup come out the same? I know frozen broccoli is much softer when it cooks. Thanks
I think the broccoli will come out softer, like you said, but that’s not necessarily a bad thing since this is a soup where all of the ingredients are super tender and soft. One thing you can try is to decrease the pressure cooking time by 1 minute.
Made this tonight, tasty!! Added sautéed chicken breasts. It was great and had enough for another full meal for the 3 of us! Thank you for posting this!
Thick chowdery soups are my weakness. Thanks for sharing!
